Commercial Milk} 



[Ten pounds of milk used.] 



From the above study it will be gathered that the amount of slime from 

 cows of the same breed and different breeds is subject to great variation, 

 but the daily production from a cow or from a herd, when determined on 

 successive daj^s, appears to be quite uniform. 



Effect of Temperature upon the Amount of Slime. 

 The temperature of the milk at the time of clarifying exerts some in- 

 fluence upon the amount, as is illustrated in the accompanying tables. 

 The cause of this is not patent unless it may be due to the coalescence of 

 colloidal particles, thus diminishing the extent of surface of the combined 

 particles and increasing the effect of the centrifugaUzing forces.
